It has been found that the reactions of polyfluoro-2,3-epoxyalkanes with ethylenediamine and 2-aminoethanol yield 2,3-di(polyfluoroalkyl)- 1,5,6-trihydro-1,4-diazin-2-ols and 2,3-di(polyfluoroalkyl)-5,6-dihydro-1,4-oxazin-2-ols, respectively. In the case of unsymmetrical oxiranes mixtures of regioisomeric heterocyclic compounds have been obtained. These reactions were found to give some by products-N,N'-bis(polyfluoroacyl) ethylenediamines and N-polyfluoroacyl-2-aminoethanols. (C) 1998 Elsevier Science S.A.
